Throttle-body annual inspection & clean Aug14/10:
- oil is now VERY evident -- carbon is now wet, and throttle plate sticks
slightly before cleaning is performed;
- intake plenum obviously coated with oil inside;
- exhaust emits brief puff of smoke when transmission is shifted at very
high revs (not visible to driver, but is visible to following car).

Funny though, the car just passed smog with wonderul numbers back in the
spring, and it starts and runs as well as ever. But gas mileage has dropped
by about 1 mpg in the past year:
2008: 29.79 mpg
2009: 29.91 mpg
2010: 28.75 mpg
(June-to-Aug, each measured interval roughly 3,000 miles)

Why don't you measure your oil consumption over a longer interval like
you do for gas mileage. Or if your goal is to be consistently stupid
why don't you compute gas mileage based on 25 miles driving intervals?

I notice you went from 344,700 349,00 without an oil change. Thought you
claimed to change oil every 3000 miles.

Because with the level dropping as far as it does, as fast as it does, I
now need to top-up more frequently than before. And if I top-up, I might as
well record what I find as I go.

That particular interval was due to my 83-year-old mother having some
serious health problems, ending up in the hospital for a couple of weeks; I
had no time to do an oil change. She lives an hour away from me one-way, so
I did a lot of driving over those two weeks.

Since about 90K miles. It's been essentially unchanged for 259K miles.

My mechanic tells me piston-slap has no bearing on engine life; the engine
will die "with" it, not "of" it.

My problem with this car is simply piston-travel distance. The jalopy
spends much of its time on the highway at about 4,000 rpm, this due to a
very low-geared 5th. Pistons can only go up-and-down for so long before the
rings eventually wear out.
